Experimental investigations were conducted to assess the influence of Abrasive Water Jet Machining (AWJM) process parameters on surface roughness (Ra) and kerf taper ratio (TR) of aramid fibre reinforced plastics (AFRP) composite. The approach was based on Taguchi’s Method and Analysis of Variance (ANOVA) to optimize the AWJM process parameters for effective machining. It was found that travers...

Technological advancement, on the one hand, makes Electrical Discharge Machining (EDM) much faster. One example of that is the presence of Wire Electrical Discharge Machining – High Speed (WEDM-HS) machine, which makes the material removal rate as high as 80 mm/min. On the other hand, it also make Abrasive Waterjet (AWJ) achieve much better quality surface and tighter tolerance. As a result, th...

Abrasive Flow Machining (AFM) is the method of finishing complex surfaces and internal channels with help extrusion pressure abrasive-laden viscoelastic polymer media. This paper based on developing a new AFM media using natural waste as base material. In article, viz. rice husk ash-based has been developed, subsequently, rheological analysis done, experimentation performed Anton-paar® rheomete...

Abstract In view of the high-precision and low-damage requirements for surface polishing hard brittle components, an abrasive jet process using a novel nozzle with specifically designed shroud was proposed. The removal mechanism investigated by simulating flow in interaction area workpiece. simulation results indicate that velocity increases greatly direction is aligned almost parallel to workp...

The wear of the focusing tube is a very important feature of the abrasive water jet machining. Of all rejected focusing tubes, 85% are worn. Similary, the age of focusing tube influences the cut geometry and quality of machined surface. With regard to the stated, wearing of the focusing tube is subject of this paper. Focusing tube outlet diameter was measured as well as its influence on the sur...

This work deals with the optimization of crucial process parameters related to abrasive flow machining applications at micro/nano-levels. The optimal combination for nano-finishing has been determined by applying a modified virus-evolutionary genetic algorithm. algorithm implements two populations: One comprising hosts and one viruses. Viruses act as information carriers thus they contribute bo...

In order to realize the uniform distribution in abrasive flow polishing of titanium alloy workpiece with curved surface, a novel method based on liquid metal-abrasive machining technology is proposed this study. Based SST k - ? model, Preston model and fluid particle tracking COMSOL software employed study dynamic characteristics under different AC electric field conditions, two-phase used simu...
